FIRE-SCREEN GATE.

SPECIFICATION forming part' of Lettersatent N o. 698,848, dated April29, 19.02.

' Application nea :rune 28, 1901. seria No. 66,444. (No moans;

vented a new and useful Fire-Screen Gate`,'of

which the following isa specification.

My invention relates to an improvement in re-screens in which saidfire-screens are pro-y vided with hinges and a lock and the reframe withhinging and locking members, as is hereinafter described; and theobjects of my improvement are, first, to hang a firescreen gate on afire-frame without marring the front of the frame or mantel; second, tohave the fire-screen gate always locked when in closed position, and,third, to provide a new, safe, and convenient handling of a tirescreenin the form of a gate. These objects are attained by attaching afire-screen gate to an open replace, as illustrated in the accompanyingdrawings, in which- Figure 1 shows the elevation of an open lireframehaving hinge members and a lockcatch. Fig. 2 is a detail perspectiveshowing hinges with elbowed arms, indentation of the rim of the screen,bolts and nuts, and-manner of alxing hinges to screen. elevation view ofa fire-screen mounted on arm and elbow hinges and carrying a lock. Fig.4 is a detail perspective showing the points of the frame on which hingemembers are affixed. Fig. 5 is a multiple View of an elevation, partlyin section, showing the several parts of the lock. Fig. 6 is anelevation View of the lock in closed position. Fig. 7 is a frontelevation of a replace, showing iirescreen gate closed and locked; andFig. 8 is a detail perspective showing the lock-plate aflixed wit-hinthe indentation of the screen.

The fire-frame D, Fig. l, is provided with hinge members h h and alock-catch fu. The hinge members are perpendicularly bored for threadedbolts m m, Fig. 2, and flat side up protrude from the left wall y offireplace..

These members h h are united to the back side of frame D at o o, Fig. 4,which sends them back into the fireplace as far at least as thethickness of the frame at its fire edge w, Fig. 4. The lock-catch fu,Fig. 1, protrudes flat side front from the right wall 'y of fireplace.In the manner of hinge' members h 7L Fig. 3 is anv lock-catch@ is unitedto the back side of frame D at p, Fig. l, and also sent back into thereplace as far as the thickness of frame shown at Fig. V4. Catch fv isnot bored.

The hinges A B, Fig. 2, are constructed with two leaves each, an upperleaf a a and a lower leaf b b, which are held and made inseparable bypivot-pins c c, upon which the lower leaf Z7 of hinge A and the upperleaf d of hinge B turn. These two leaves b and dare united to the screenC at d d, Fig. 2, and owing to their shape carry the screen awayfromframe D when ,the screenis swung open. The upper leaf a of hinge Al andthe lower leaf b of hinge B are made with arms c e, which are crooked byelbows g g. At the end of arms e e bored flanges ZZprotrude from thelower edges of e e and will rest u'pon the upper side of hinge members hh when bolted thereto.. From elbows g g to anges l Z arms e e may be anynecessary length, and in width will conform to the thickness of theirhingeleaves. Hinges A B. being united to screen C at CZ d, the arms eepass under au indentation of the rim of the screen at ff, Fig. 2, andare carried by elbows g g around the fire edge of the frame D, Fig. 4.Flangesllof arms e e are then connected with the upper sides of boredhinge members h 7i, at o o, Fig. 4, and are made fast with threadedbolts m m and nuts s s, Fig. 2. The hinges are thus brought into actionin frontof the lire-frame, although hung from hinge members hh on leftwall y within the fire-place. This manner of hanging the screen-gateinsures against defacement of the frame or mantel and leaves no hinge orlocking members in sight when the screen is taken down and thefire-front put up for the summer.

lIn the construction of the lock in Fig. 5 knob E is made with a squarehollow extension or handle b', which extends into the knob, as shown atc'. the hollow handle o has a small threaded boring'b, as shown in Fig.5, to receive a screen, the boring running horizontally with the handle.The size of the boring depends on the thickness of the metal. At the endc of hollow handle b a cavity d as deep as the thickness of the metalextends across the floor or lower side of handle b', as shown in Eachside of the open end of f vIO the exposed view of the inner parts ofknob E. A pin g', aixed to a push-button j", extends up through anapertureh' in knob E and passes into a perforation It of the lower sideof handle h at c. The second part of the lock consists of two steelprongs Z Z', having anges m' m', made in one piece and bent in the formshown in drawings. The prongs must be thinenough to provide an easyspring when pressure is brought to bear upon them.

Precisely in the center of the curve at n.' av

steel rod p is firmly affixed. This rod eX- tends toward the flanges mm', and at r will be the thickness of lock-catch fu short of the lengthof prongs Z Z' whenlanges m' fm are brought together. A rod t', having atumbler s', is pivoted at u', so that the tumbler will easily fall intocavity d of handle b. Rod t has an overhanging edge s at tumbler s' tocatch the pin g when button f is pushed. A guard fu', made in thefformof the letter H and perforatedl at fu2 'v2 r3, has a cross-piece w',supporting upper side guards as cc and lower side guards 56:12. Guard ccovers the open end of handle b and is made to permit the prongs Z' Z towork in. The upper and lower side guards az and cross-piece w will thuskeep the prongs Z Z in place when inserted intoth'e handle b' andprevent the handle from slippingout of the plate y when the lock isopen.

The screen C is indented at 2:' z', at which points a lock-plate y isaflixed firmly to the screen and its rim. The plate y' is provided withan aperture e". On the front side of the plate the aperture is rimmed'tosteady handle b and is made to permit the handle to slide in without toomuch freedom.

Having thus described the construction of the several parts of thelock,a furtherexposition will show how they are brought together. Theplate y', Fig. 5, is firmly united to the screen and its rim at thepoints z', the indentation of the screen permitting the plate to presenta lat front'. The handle b' is inserted into the aperture s, and theprongs Z' Z are then inserted into the hollow of handle b and held inplace by guard 1;,which is passed over rod p', through perforation v3,and screwed to the handle at threaded borings b" and perforations 112.This unites the lock in an open position to the screen. To close thelock, the screen is swung against the ireframe D at 1o, Fig. 1, whichbrings the end fr' of rod p', Fig. 5, against the flat or front side oflock-catch fv of frame D. Thus is formed a point of resistance againstwhich the'han'-4 dle lb is pressed, the result being that as rod p cango no farther the handle b' is pushed upon the prongs Z' Z until thetumbler sfalls into cavity d' in handle Z7', which happens when thehandle is pushed far enoughA upon the prongs to bring the a'n'ges m fm.together `on the otherside of catch o. `This act locks the screen, as inFig. 7, and holds the lock F securely closed, as in Fig. 6, by thetumbler s being in cavity d', the ypointr of rod p' being against thenear -side of'lock-catch u and the'llanges'm` m having been broughttogether on the far side of catch fu. To release the lock, the buttonfin knob E is pressed upward, which sends the pin g through theperforation k in handle b and against the overhangin g edge s" of rodt', thereby raising the tumbler s out of cavity d' and allowing handle bto be pulled 0E the prongs t Z', thus opening the lock and releasing thescreengate from its locked position.

I am aware that fire-screens are in general use and have been mounted indierent forms; but I am not aware that the combination as herein setforth vhas ever been used.

What I claim-as my invention, and ldesire to secure by Letters Patent,is-

l. The combination, in a lire-screen gate, of a lire-frame having hingemembers 71, h, and lock-catch fv, affixed tothe back side of the frameat the fire edge, a fire-screen mounted on arm and elbow hinges A B, tobe united to the hinge members on the frame, the arms e e and elbows g gaffixed to said hinges an indented rim for the passage of hinge-arms,and the lock F` aixed to the screen to coperate with the lock-catchonpthe frame, all substantially as set forth. l

2. A ure-screen gate comprising a catch and a hinged screen having anindentation, a lock-plate therein, a lock having a knob carrying a pinand push-button, a hollow handle aftixed to the knob, spring members anda stop member, movable within said handle and having a rod and tumblerto be operated by said push-button, said spring members coperating withthe catch above mentioned; all substantially as shown.

In testimony whereof I have signed lmy name to this specification in thepresence ot' two subscribing witnesses.
